ABSTRACT

A new and distinct  Mandevilla  plant named ‘Tsuruhanbestpinki-1’ of upright and vining plant habit, relatively small glossy foliage, freely branching habit, freely flowering habit, and being in full flower around Mother&#39;s Day as illustrated.

Latin name: Mandevilla sanderi.

Varietal denomination: ‘Tsuruhanbestpinki-1’.

This application claims priority of Japanese application for variety registration no. 22770, filed on Jul. 17, 2008. All content of the application is incorporated herein by reference.

BACKGROUND OF THE INVENTION

In May, 2003, to obtain this variety, a pink-based nameless variety of a culture line possessed by Applicant was crossbred with mixed pollens of nameless varieties of a culture line possessed by Applicant in a farm owned by Applicant in the town of Yusui-cho, Aira-gun, Kagoshima Pref., Japan. The pink-based nameless variety has a longer distance between joints in a stalk and a larger number of blooming flowers compared to ‘Tsuruhanbestpinki-1’. Each of the nameless varieties has a longer distance between joints in a stalk but with many branches.

In February, 2004, after the above crossbreeding, a plant was grown and a resultant seed was planted into a soil on the farm to grown (germinate) and then bloom. This planting was carried out with the expection that some varied plants could be obtained.

In April, 2005, from several hundreds of the flowering plants obtained by the above planting, one compact individual plant having a shorter distance between joints in a stalk and extemely larger number of blooming flowers appears. Then, to obtain a compact plant variety having a shorter distance between joints in a stalk and being extremely easy to bloom, the above compact individual plant was selected and a branch (stem) thereof was removed and inserted in a soil to be grown (cutting, i.e., vegetative reproduction) and such a vegetative reproduction was repeated for propagation.

In June, 2006, the culture was completed after ensuring uniformity and stability. In other words, it was confirmed that the compact plant variety having a shorter distance between joints in a stalk and being extremely easy to bloom can be obtained with uniformity and stability, the above repetition was completed.

SUMMARY OF THE INVENTION

-   -   1. Upright and vining plant habit.     -   2. Relatively small glossy foliage.     -   3. Freely branching habit.     -   4. Freely flowering habit.     -   5. Being in full flower around Mother's Day.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Mandevilla.

FIG. 1 is a panoramic view of the cultivation area, wherein the plants are 28 months old.

FIG. 2 is a close-up view of the plant's flower, wherein the plant is 7 months old.

FIG. 3 is a diagrammatic view of the plant's flower, wherein some petals are removed so that a color of the inner side surrounded by petals and colors and shapes of the stamen and pistil can be seen.

FIG. 4 is a view of another plant variety for comparison, the other variety's name being ‘Peach mini of Sun parasol’. It is considered that ‘Lipgalpinkyflash 2’ is the most similar variety to ‘Tsuruhanbestpinki-1’. The characteristics table for ‘Lipgalpinkyflash 2’ filed in a Japense plant variety application is attached herewith for reference.

FIG. 5 is a view of two plants of the other plant variety for comparision, the other variety's name being ‘Peach mini of Sun parasol’. It is considered that ‘Lipgalpinkyflash 2’ is the most similar variety to ‘Tsuruhanbestpinki-1’.
